What is a twelve-year-old girl to do when she finds herself in the silver boom town of Tombstone, Arizona, in 1880, and her only home is a brothel and her only parent is a drug-addicted mother? If she is Carissa Beaumont, she outsmarts the evil madam and figures a way out.
After tricking the madam, Miss Lucille, into summoning a doctor for her mother, Lisette, she discovers that Miss Lucille has been drugging her. She and the kind doctor make a plan to try to save Lisette by dosing her down on the drug.
